Abstract
A device for connecting plates and/or rods of the light construction type made of wood, plastic or the like, with junction pieces having a plurality of threaded holes whose axes intersect at the center of each junction piece. Tap bolts are disposed in the area of the plate corners and/or the rod extremities so they can rotate and slide axially in the planes of the plates and/or along the axes of the rods, which can be screwed into the threaded holes of the junction pieces. The tap bolts are mounted in dowel-like shells which have at their outer ends an abutment for each tap bolt. The shells are pressed and/or glued into boreholes in the area of the plate corners and/or extremities of the rods. A drive-collar is mounted on the shank portion of the tap bolts protruding from the shells.
